Title: Improvements in or relating to switching devices for impedances having inductive characteristics
IPC: G06K13/20
Filed: 1962-01-25
Abstract: 995,902. Controlling clutches. ELECTROLOGICA N.V. Jan. 25, 1962 [Jan. 25, 1961], No. 2842/62. Heading F2L. [Also in Division H3] A switching circuit for energizing alternatively two inductive loads 41, 42 such as the drive and brake magnets of a punched tape reader, comprises two alternatively conducting switching devices such as transistors 21, 31, two auxilliary coils 51, 52 and two rectifiers arranged substantially as shown. When transistor 21 is conductive and 31 non- conductive current flows through load 42 and inductor 52 and also through inductor 51. When the conductivity of the transistors is reversed current flows through transistor 31 to load 41 and inductor 51, the rise in current is being speeded by the energy stored in the inductor. Load 42 is de-energized but continues in inductor 52 to assist the re-energization of load 41 when the conductivity conditions of the transistors are again reversed. Zener diodes 71, 72 or capacitors (Fig. 3, not shown) absorb the back e.m.fs. and it can be arranged that the rate of rise of current in one load is the same as the rate of decay in the other so that in the tape reader referred to the tape tension is maintained constant.

Abstract: 371,886. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. and WRIGHT, E. P. G., Columbia House, Aldwych, London. Jan. 29, 1931, No. 2892. [Class 40 (iv).] Single-motion finder-switches have a number of spaced resting positions on which the unsuccessful switches distribute themselves after hunting for a call. When more than half of the switches of a group are busy, alternate resting positions may be cut out so that the distribution of the idle switches will be more uniform. Detailed operation. The Figure shows finders JF with two sets of wipers, employed for extending calls incoming over two-wire junctions to bye-path apparatus. When a junction is taken into use relay L operates energizing group relays GS, GSS, GSR, GY, GZ. Relays GA, GB, .., one associated with each resting position, are also operated and lock over their upper windings. Relays ST in finders associated with free conversational switches are operated and locked, connecting up the driving magnets JM. When the calling junction is found relay X (or Y) operates, short-circuiting its right-hand winding to release GS which falls back quickly owing to its opposing lefthand winding. Relay K operates over wiper 3 (or 4), relay L being locked in parallel with K. Impulse relay A operates at first in series with L and then over the loop, a reversal of current over the junction being thus effected. The release of GS, GSS, GZ, GY connects relays GA, GB, .. to the various resting positions which are all associated with the lower set of wipers. The unsuccessful switches continue to hunt and as each finds a resting position relay Y operates, unlocking ST and short-circuiting GA which in releasing renders the position busy to other idle switches and releases Y in the associated switch. When more than half of the switches are busy, marginal relay GM operates maintaining GZ locked so that relays GB, .. corresponding to alternate resting positions are not connected up to mark their associated positions selectable. When a finder becomes idle after use, a relay T (not shown) energizes ST and the finder advances in search of a resting position. Arrangement of junctions in finder banks. (1) Late-choice junctions in the outgoing- selector banks are connected to the finder banks at points near to a resting position so as to reduce the over-all hunting time. (2) Junctions having the heaviest traffic are connected to points in the upper bank corresponding to the resting positions in the lower bank. For a call over such a junction relay X operates before GS and no movement of the finders takes place. (3) Junctions connected to points farthest from the resting positions may appear twice in similar positions, one of these following a resting position which is always operative. Faulty junction. If a looped junction is forcibly released, the removal of earth from the holding wire releases L but K remains locked over the loop to hold the junction out of action.

Title: Bioglass coated a12o3 ceramics
IPC: C04B41/50
Filed: 1977-01-27
Abstract: The process consists in employing a glass whose thermal expansion coefficient is different from that of the ceramic. A first vitreous coating (2) is deposited on the ceramic (1) and is heated to ensure welding of the coating onto the ceramic by ion diffusion. The whole is cooled to create microfissures (3) in the vitreous coating layer as a result of the thermomechanical stresses which are generated therein. This first coating is covered with at least one additional layer (5) of biologically active glass, which is welded onto the first layer. The product obtained by making use of this process can be employed for the production of internal prostheses capable of replacing at least a part of a bone and requiring no cement. <IMAGE>
